Fitness and Freshness graph for Run activities

I, as most use Strava for running and cycling. I don't know the actual calculation, but the tool Training Peaks allows you to map your TSS, IF and training stress balance for running. This would be a great feature to add in to help with training for events.

Before you assign valuable resource into looking at Justin's issue please can you let us know when Fitness and Freshness will be available to runners (which as you know is the purpose of this thread!).

I have just joined premium purely to use the fitness / fatigue chart across running, cycling and swimming as I've just started training for triathlons. Feel very cheated the write up on what you get with premium doesn't state this up front. I've cancelled my premium account and will use training peaks instead.

Hi. I'm looking forward to when this feature is made available to all sports with HR data. Any update on when it will be available? The description on the fitness & freshness page says it will be available to runners soon (it has said this ever since i became a premium member in late 2015)

There are a few activity types that do not yet have suffer scores (Nordic Ski and Backcountry Ski) and will not show in the graph. However, we are working right now to get all activity types updated so that any activity with heart rate will be included in the Fitness & Freshness feature.

As to a couple of other comments - I've got a Garmin 735xt, and the Optical HR has come through (kind of)

If I look at a 6 month period, the fitness profile looks about right - sharp peaks for activities, with a decline. However, recent runs are really odd. Several have negative suffer scores, which I just don't get? Anyone else seen this?

Fitness & Freshness il significato dei numeri sul grafico

Great to see running added to the F&F graph, but.... how is the running score calculated? It seems it is based on suffer scores which are based on HR zones. I use HR zones for both bike and run, but my training zones are different (I don't have a PM). I customised the zones for the bike (lower HR), but this results in my run suffer score being inaccurate. As an example, a 30min easy run had a suffer score nearly twice as big as a 1 hour interval bike session. The result.... the F&F graph is giving me false information. Is there a way to have separate running and bike HR zones customised (like Garmin and others do)? Or can the run suffer scores be calculated by Pace Zones? Thanks

I had one run where my HR got all screwed up and I ended up with average HR of 128 and my suffer score being 88 (14mi@2hrs). For a run of this nature, my suffer score should be in the 300's. Is there anyway to edit the suffer score?

@Elle, HR zones / max HR _per activity type_ has been requested for years, and has been actively ignored by you.

I have cancelled my premium subscription long ago since the Strava data becomes useless - either Suffer Score for cycling is off, or it's off for running, since my max HR differ for running and cycling (as it always does).

All the Strava data analysis is based on HR and HR zones, so not being able to have different zones for different sports is unbelievable stupid. Garmin, Sport Tracks, they all have it, and I am a paying Sport Tracks customer, btw, so you have lost my money for the past few years (as you have with others).

I'd be very interested in what happens with this support ticket and the reasons behind not implementing something in so obvious demand for so long. Making this kind of new fancy F&F stuff, with the underlying data being useless... interesting, but nothing I would dream of paying for.

Hi Elle,
It is working well for me thank you. However my Garmin has just died and I am.having to use an old monior which doesn't sync with Strava whilst I await a replacement. The next step would be to be able to manually add heart rate data so this wouldn't cause a false drop in fitness and elevation in freshness om the graph. It would also mean I could include my swims in the data.
Thanks

@Calle, I don't understand this logic. Not that I disagree, (I don't do much cycling), but myself and a friend at work have been talking about HR/Suffer score for different activities.

Surely HR/zones should be consistent across exercises? If I'm exercising close to my maximum heart rate, surely this generates the same suffer score points whether it's running or cycling?

As for the feature generally, while I'm glad it's made an appearance for running, I'm baffled how it got through testing - my support ticket (thanks for raising Elle) immediately said my running activities were skewed because of Power metrics in previous activities (I had used Stryd a few times). So does the Heart Rate Only activity filter actually do anything?
